Miku Ikuta, a 21-year-old college student with a youthful face, was planning to relax with her boyfriend under the kotatsu. But suddenly, the doorbell rings. When she answers, her boyfriend's senior appears, saying, "I brought some booze—let's drink together!" Without giving her time to refuse, he enters the house and sits beside her under the kotatsu. Assertively declaring, "Come on, drink up! I bought this, so it's gotta be good!" he starts gradually touching her thighs. Miku resists slightly, but is overwhelmed by his forceful attitude. Her boyfriend, completely drunk, falls asleep under the kotatsu, leaving the senior free to do as he pleases. He yanks off her clothes and hungrily licks her soft, jiggly breasts. Then, spreading her into a wide M-shaped split, he begins passionately eating her pussy right next to her sleeping boyfriend. Initially hesitant, Miku gradually loses the will to resist and starts moaning. Just as her boyfriend suddenly wakes up, the senior thrusts his rock-hard cock deep inside her, stuffing her mouth with thick, noisy blowjob sounds—ending the scene in complete chaos.
